From the calculus class. Please tell me the steps for question 3).

I attached the steps for a similar question at the end. Thanks for your help!

Question:

Handout - Difference Quotient Practice The quantity f ( x + h) - f(x) h is called a difference quotient and has important uses in the study of calculus. The example below illustrates a step-by-step process for evaluating a difference quotient. Example: Given the function f(x) = 3-2x, find and simplify the difference quotient (2+ h) - f(2) h Step 1: Find and simplify f(2 + h). f (2 + h) = 3-2(2 + h) = 3-2(4 + 4h+ h-) =3-8-8h -2h- =-5-8h - 2h Step 2: Find and simplify f (2+ h) - f(2). f (2 + h)-f(2) = (-5-8h- 212)-(3-2(2)?) = -5-8h-2h - (-5) = -8h - 2h- Step 3: Find and simplify f (2 + h) - f(2) h f(2 + h) - f(2) -8h - 2h- h h h(-8 -2h) h = -8- 2hExercise: Find and simplify the difference quotient f (2+ h) - f(2) for each of the following functions. h
